Crystal-free Zone in a Glass-Ceramic Dish
28 May 2019 | | Contributor(s):: Adam Powell
Estimate the thickness of the crystal-free surface layer in a glass-ceramic dish by relating a heat equation solution to the T-T-T diagram.
Chemical Vapor Deposition
Calculate boundary layer sizes and deposition rate profiles along substrates on the bottom of a box-type chemical vapor deposition chamber.
Freezing by Radiation and Convection
16 May 2019 | | Contributor(s):: Adam Powell
Use radiation and a heat transfer coefficient to estimate the initial rate of solidification of the solid shell at the top of a casting while the temperature in the shell can be considered uniform, then set up the equation for mixed conduction/convection-radiation limited cooling.
Heat Conduction and Diffusion in Alloy Casting
Derive temperature and liquid concentration profiles during die casting of a roughly plate-shaped alloy part.
Electron Beam Centrifugal Atomization of Metal
Use a heat balance to calculate electron beam power required to continuously heat and melt metal as it is atomized, including heat losses from the top surface due to evaporation and radiation.
Cast-a-Box: Casting Conditions and Macroporosity
07 Apr 2019 | | Contributor(s):: Adam Powell
An illustration of three-dimensional finite difference simulation of heat conduction with phase change and complex boundary conditions, this requires students to adjust boundary conditions to make the top surface of a regular hexahedral "casting" to freeze last, eliminating...
Nanotechnology Invention and Design: Phase Changes, Energy, and Crystals
11 Jan 2017 | | Contributor(s):: Daniella Duran
This 3-part lesson introduces the nanoscale effect of various energy inputs on the crystal lattice of a smart material, Nitinol, and then invites students to become nanotechnology inventors. Students will first explore how energy exchanges lead to solid-state phase changes at the macroscale and...
